Felix Fietkau 8a30930563 ath9k_hw: make bluetooth coexistence support optional at compile time
Many systems (e.g. embedded systems) do not have wifi modules connected to
bluetooth modules, so bluetooth coexistence is irrelevant there. With the
addition of MCI support, ath9k picked up quite a bit of extra code that
can be compiled out this way.

This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for
querying the bluetooth coexistence scheme, allowing the compiler to
eliminate code that uses it, with only very little use of #ifdef.

On MIPS this reduces the total size for the modules by about 20k.

Luis R. Rodriguez 7322fd1929 ath9k: move hw code to its own module
hw code for Atheros 802.11n hardware is commmon between
different chipsets. This moves this code into a separate
module, the next expected user of this code will be
the ath9k_htc module.

The ath9k/ dir is now selected by ATH9K_HW, an option which
gets selected by either ath9k or ath9k_htc, but remains
invisible for user menuconfig configuration. If either
ath9k or ath9k_htc will be compiled into the kernel
ath9k_hw will also be compiled in.

Luis R. Rodriguez 75d7839f4c ath9k: move driver core helpers to main.c
Keep on btcoex.c only hardware access helpers, move the
driver core specific code to main.c. To accomplish
this we had to split ath_init_btcoex_info() into two parts,
the driver core part -- ath_init_btcoex_timer() and the hw
specific part -- ath9k_hw_init_btcoex_hw_info(). This
highlights how ath_gen_timer is part of the driver core, not
hw related, so stuff that into ath_btcoex struct.

The ath9k_hw_btcoex_init() code is now put inline on
ath_init_softc() through a switch to it easier to follow,
since we did that we can now call ath_tx_get_qnum() from
the main.c instead of btcoex.c

values upon drv_start()
